Definitions

  • the present invention relates to demucilaged flax sprouts easy to digest, suitable for direct human consumption and utilizable in different fields such as in food industry, therapy and animal husbandry.
  • the invention also relates to the production process and applications of the demucilaged flax sprouts.
  • the present invention further relates to a process for recovering mucilaginous substance originating as a by-product in the production process as well as to various applications thereof.
  • the flax is a highly nutritious plant. It could be advantageously utilized in human nourishment on account of its high protein and oil content. Compared to other nutritive material sources it is the flax that contains the greatest amount of unsaturated fatty acids including alpha-linolenic acid of type omega 3 which is essential for the human organism [see Table 1; Bene et al.: “Szappanok és mosószerek” (Soaps and detergents), Müuszaki Könyvkiadó, Budapest, 1957].
  • the flax seed as far as the composition of the contained nutritive materials is concerned, has excellent properties [see: USDA National Nutrient Database for Standard References, Release 17 (2004)]. Furthermore, it contains phyto-hormones (lignans) in great quantity which certifiably have anticancer effect (see e.g.: Carcinogenesis 20(9): 1831-1835, 1999; Nutr. Cancer 43(2): 187-192, 2002). On the basis of the properties of the contents it is desirable that the flax should be an integrated part of the nutrition and it should be utilised in the food industry in a wide range. For the time being the utilisation of the flaxseed, is however, for many reasons, very limited.
  • the seeds can, for example, be sprouted on some kind of carrier material (soil layer, cotton fabric, diaper material, etc.), and the green parts of plants can be consumed only by harvesting the cotyledonous plants.
  • carrier material soil layer, cotton fabric, diaper material, etc.
  • This application is very elaborate, and its application is not suited for large scale production.
  • Another disadvantage is the fact that when the cotyledons become green, already significant energy has been drawn from the seed, the development of bitter tastes starts, and the decomposition of multiple unsaturated fatty acids begins, resulting in a limited storability of the plant material (10-12 days).
  • Barker D. et al. introduced a sprouting process in order to increase the relative amount of alpha-linolenic acid in the sprout product.
  • the aim of the procedure reviewed in the mentioned patent publication document No. WO 03/003854 was not the removal of mucilage hindering the digestion, and does not solve that problem at all.
  • the composition of the sprout material was improved with this introduced method, it is very likely that the absorption of these compounds does not happen in the animal and human organism.
  • the method elaborated by Barker D. et al. does not allow for the surface sterilization according to the requirements of food-hygiene.
  • the flax seed mucilage is by itself an interesting and valuable material. A lot of articles dealt with its investigation (see e.g.: Journal of Food Science 54(5): 1302-1305, 1989; Food Hydrocolloids 17(2): 221, 2003; Chromatographia 58(5-6): 331-335, 2003).
  • the flax seed mucilage is indigestible for the human organism, therefore this material is called water-soluble fibre material (Philips G. O., Food Hydrocolloids 17(2): 221, 2003). According to experiences this material forms a thin layer on the stomach wall and the villi; this layer has both a strong laxative effect, and also prevents the absorption of nutritive substances. Thus it can be utilized as an additive for slimming agents.
  • the aim of present invention is to eliminate the above-mentioned problems and to bring the flaxseed into a suitable form for direct human consumption.
  • this aim can be reached by removing the mucilage from the surface of flax seed. Through this process the flax seeds are deprived of mucilage, and then the seeds are germinated. The sprouted flax seed become accessible for the gastric juices, and the hard to digest oils are mobilized in the sprouting flaxseed. The flax sprout thus becomes suitable for direct human consumption or can be utilized as a basic food material.
  • a further aim was to preserve the vitability of the seeds in order to retain their ability to sprout and also to gain access to their inherent values.
  • the objective of the present invention has been to work out a process suitable for completely removing the gel-like mucilage from the surface of the flax seed and thereby to make the surface of flax seed suitable for direct sterilization and sprouting.
  • the mucilaginous material from the flax seed steeped in water could not be removed by washing, pressing and intensive agitation.
  • the expression “removal” means an almost 100% removal, as the seeds can be sterilized only in this way.
  • the mucilaginous material has a stable gel structure, and that this structure is stabilized with cross-links.
  • the enzymatic treatment of flax seeds steeped in water in advance does not give any result at all.
  • the experiments of digestion directed to the gel from outside were unsuccessful; nevertheless, this method proved to be the most suitable from the point of view of retaining the sprouting ability.
  • the mucilaginous material separates from the surface of seed on a gentle mechanical influence as a thick, mucilaginous solution.
  • the invention relates to demucilaged flax sprouts derived from flax seeds deprived of mucilage.
  • mucilage and “mucilaginous material” are the same.
  • the invention further relates to a process for the production of demucilaged flax sprouts through the following steps:
  • step (ii) removing the mucilaginous material separated from the surface of flaxseeds during step (i);
  • step (iii) cleaning the flax seeds obtained by step (ii) for mucilage by washing
  • the invention further relates to a process for the recovery of mucilaginous material separated during the enzymatic treatment of flaxseed, comprising the precipitation of gel-like mucilaginous material separated with the process according to this invention from its aqueous solution with an organic solvent suitable for precipitation of polysaccharides, the dehydration, desiccation and pulverization of the mucilaginous material, and optionally processing it further.
  • the invention further relates to the application of mucilaginous material obtained in this manner, first of all for cosmetic, pharmaceutical, microbiological and industrial purposes.
  • the flax seed used as a basic material can be the seed of a flax variety, e.g. Linum usitatissimum cv. Brown, L. usitatissimum cv. Goldline and the like.
  • the aqueous enzyme solution of the desired composition can be prepared from the necessary enzymes.
  • the seeds are swollen in the enzyme solution which is prepared beforehand.
  • the flax seed may be placed in plastic bags with small holes or plastic net, the mesh of which is about 0.2 mm.
  • the enzyme solution contains pectinolytic and cellulolytic and optionally proteolytic enzymes.
  • pectinolytic enzyme pectinase, e.g. Macerozyme R-10 or a pectinase derived from Aspergillus niger
  • cellulolytic enzyme cellulase e.g.
  • glucuronase helicase or sulfatase; as a proteolytic enzyme lysosyme, protease and the like
  • a pectinolytic (pectin-splitting) enzyme is used together with a cellulolytic (cellulose-splitting), preferably pectinase derived from Aspergillus niger and glucuronase.
  • a pectinase is used together with lysosyme, which is well known to be a multifunctional enzyme.
  • a pectinolytic enzyme is used together with cellulolytic enzymes, namely glucuronase and sulfatase.
  • the aqueous enzyme solution contains the pectinolytic enzymes in 1-10 U/ml, preferably 1-5 U/ml concentration, the cellulolytic enzymes in 2-50 U/ml, preferably 5-15 U/ml concentration and the proteolytic enzymes in 10-500 U/ml, preferably 50-200 U/ml concentration.
  • the composition of the enzyme solution depends on the flax variety.
  • the supernatants originating from fermentation broth of micro-organisms producing specific extracellular enzymes, as pectinolytic, cellulolytic and proteolytic enzymes are used as aqueous enzyme solution.
  • the supernatants are adjusted to pectinase enzyme activity.
  • the fermentation broth can be originated from fermenting bacteria or fungi, e.g. Trichoderma sp., as Trichoderma rosea, Glyociadium catenulatum and the like.
  • the mucilaginous material originated from the process according to this invention can be used as fermentation media, too.
  • the fermentation broth is centrifuged, the supernatant is separated and optionally sterilized by sterile filtration, or by treatment with chloroform, and the like.
  • the fermentation broth is optionally filtered to be cell-free.
  • the pH of enzyme solution is mildly acid, preferably 6.5, which can be adjusted with organic or inorganic acids or with acidic salts.
  • hydrochloric acid, acetic acid or potassium dihydrogen phosphate, preferably acetic acid can be used.
  • the seeds are treated with an enzyme solution of a volume ratio from one-and-a-half to two, preferably one-and-a-half parts calculated to one volume unit of the seeds. During this treatment the seeds take up the enzyme solution, then they are incubated at temperatures of 20-30° C., preferably 25-28° C. for 6-24 hours, preferably for 18-20 hours. Then the seeds are swollen to their water absorbing capacity (about fivefold of dry seed volume).
  • the swelling can be promoted with a gentle mechanical agitation, preferably stirring.
  • the aqueous, gel-like mucilaginous material is separated from the seeds by applying a mild pressure, preferably pressing to the wet seed volume. In this manner about 90% of the mucilaginous material can be separated. Because the sterilization of seeds is necessary for the germination, the rest of mucilaginous material has to be removed from the seeds. It can be achieved by an intensive watery washing. The washing of seeds is continued until the wash liquid turns transparent (not opalescent), and mucilaginous material cannot be detected in the wash liquid, neither by touch nor with a chemical method. Then the free water between flaxseeds can be removed by draining, vacuumsuction or centrifugation, and the seeds obtained in this manner are directly used for sprouting.
  • the seeds perfectly cleaned of their mucilage are sterilized.
  • different sterilizing agents e.g. sodium hypochlorite, hydrogen peroxide, hyamine and the like are used.
  • the seeds are preferably sterilized in a sodium hypochlorite solution of low concentration for 30-50, preferably 40-45 minutes during continuous stirring, then the sterilizing agent is removed by washing with water, preferably by repeated washings, and the free water is removed by one of the above mentioned procedures.
  • the seeds obtained in this manner are germinated by spreading them in a layer of 2-3 cm.
  • the germination can be carried out in the usual way, preferably in darkness, at temperature 18-30° C. for 6-48 hours.
  • the humidity left on the seeds is sufficient for them to sprout.
  • the sprouts are grown up to a length of about 1-5 mm, preferably 2-4 mm, then they are harvested and are used directly or after drying.
  • the flax sprouts obtained in this way are free from mucilaginous material. This is proved by the fact that the liquid flowing out after repeated watery steeping of flax sprouts do not contain sugar-like materials after acid treatment. They can be stored well and can be utilized directly for consumption or in food preparations. It was found that for example by packing the sprouts in plastic foil, and storing them at a temperature of 4° C. for 60 days no loss in quality occurred, e.g. the original taste and consistency was preserved.
  • the objective of the preparation of industrial food products containing fresh flax sprout is that the flax sprout used as an additive should be kept in a active, not decayed condition for a time as long as possible.
  • Our aim has been that the fresh flax sprout should preserve its original taste and consistency in the product.
  • the temperature during the processing should not exceed temperature 40-45° C.; in this manner the premature decay of flax sprout and the oxidation of multiple unsaturated fatty acids can be prevented.
  • Another very important point of view is, however, that the total osmotic pressure of food (in an aqueous medium, e.g. cheese), to which the flax sprout is added, should not exceed the isoosmotic value. In the case of high osmotic pressure the flax sprout looses water during the storage and its consistency changes.
  • the flax sprout can be dried and crushed, and the product obtained in this manner can be stored similarly as a kind of cereal, e.g. wheat or wheat meal.
  • the drying is performed gently, preferably under temperature of 30° C. in such a manner that the flaxseed sprouts are dried to 75-90 percent of their initial seed weight, preferably to 80-85 percent of weight.
  • the product obtained this way can be consumed as it is, or it can be mixed into food or animal fodders.
  • it can be also used as a food supplement or nutriment or in a food preparation, first of all as a supply of essential fatty acids and phyto-hormones.
  • auxiliary materials usually employed in the food industry or in the preparations of pharmaceuticals as e.g. maltose, maltodextrine, binder materials, aroma materials, sweeteners, food colouring agents, etc., or together with materials usually employed in the preparation of nutriments, as e.g. protein, carbohydrate, minerals, vitamins, etc., or it can be pressured to tablets or encapsulated in a manner known per se.
  • flax sprout obtained in this manner is free of mucilage and therefore likely to be absorbed well, and its valuable components can be utilized in the living organisms.
  • Another advantage of the process according to the present invention lies therein that 90% of the separated mucilaginous material originating as a by-product can be recovered and utilized.
  • the squeezed, concentrated mucilaginous material can be precipitated with organic solvents suitable for precipitation of polysaccharides, thus, e.g. it can be precipitated with alcohols or chloroform.
  • the squeezed, concentrated mucilaginous material is precipitated preferably in 50% (v/v) aqueous ethanol solution at a temperature of 4° C. after leaving it at rest for at least 12 hours, and it can be separated well by centrifugation.
  • the precipitating agent e.g. ethanol
  • the precipitate obtained by centrifugation can be dehydrated with 96 percent ethanol, and the dehydrated precipitate is centrifuged again, then the precipitate obtained in this manner is dried. At the end of this process an amorphous material is produced which can be pulverized and packed. The flax mucilaginous material obtained in this manner can be perfectly dissolved again in water.
  • the mucilaginous material obtained by this process can be utilized in many fields. It can be utilized in cosmetic agents, e.g. in body lotions as an emulsifying agent and foaming material. It can be also utilized for food industrial purposes as a consistency improver. It can be used in microbiological processes as a culture medium or as a component of culture media for the cultivation of pectinolytic micro-organisms and/or micro-organisms utilizing polysaccharides, e.g. Aspergillus niger or Glyocladium catenulatum. In fact, it can be employed as a lubricant with a water basis for e.g. lubrication of rotating instruments.

  • a rough preparation is prepared in a quick-blade grinding machine.
  • the quick-blade grinding machines are suitable for this purpose because it can be ensured that during the grinding the temperature does not exceed 30° C.
  • the grist obtained in this manner can be stored for a long time similarly to the grist prepared from cereals.
  • the flaxseeds treated according to Example 1-3 perfectly swollen in water and held in bags are put in a press (e.g. wine-press is suitable), then the mass are pressed to such an extent that 90% of mucilaginous material should be pressed out and the seed should not injured.
  • the pressed out, concentrated mucilaginous material is mixed with 96% ethanol in a ratio 1:1. From the about 50-50% water-ethanol solution the mucilaginous material is allowed to precipitate standing at least 12 hours at 4° C. After precipitation the mucilaginous material can be removed by centrifugation (e.g. preparative centrifuge, separator) and the alcohol can be recovered.
  • the precipitate-obtained in this manner is almost dehydrated with 96% alcohol, then the pure precipitate is dried (at 120° C.). After drying a hard amorphous material is obtained, which can be packed and utilized. The thus-obtained mucilaginous material can be completely dissolved in water.
  • Example 9 5-10 grams dried and pulverized mucilaginous material prepared according to Example 9 are added into 1 liter potato extract (the liquid of boiled potato). This mixture is sterilized at 120° C., then after cooling is inoculated Aspergillus niger inoculum and the liquid is fermented in a manner known per se. The culture of Aspergillus niger is harvested after 48 hours and is processed further.
